CBS News has uncovered a serious pricing problem with HealthCare.gov. It stems from the Obama administration's efforts to improve its health care website. A new online feature can dramatically underestimate the cost of insurance.

The administration announced it would provide a new "shop and browse" feature Sunday, but it's not giving consumers the real picture. In some cases, people could end up paying double of what they see on the website, CBS News' Jan Crawford reported Wednesday on "CBS This Morning."
